Anyone running the Resonator K on a ~12.5" 5.56? Im looking for a can thats suitable on both a 300 blk and 12.5 5.56. I know making a 12.5" 5.56 hearing safe is a tough ask, and I know 30 cal cans on 5.56 give up a fair bit in performance. However, does it suffice in taming the blast? 300 blk is secondary, so if perofrmance is just garbage, I will go back and decide if a dedicated 5.56 is worth the time and money investment.
